Anything wrong about MM...?

My first topic/post here, but I'm really pissed off about "so-called recent balanced MM" from WG!
Is there legit explain about MM?

How the Hell is able to compare tier 6 Scout against tier 7 one if there was only FUCKIN' one of them in each team?!?
Or we all don't know the ability of Light Tanks and their specs over the same tier in one battle...
I was so shocked about previous battle MM, that I forgot to take print screen - but this one remembers me to do it.
In previous one, there were 3 Luchs on each side and they were top FUCKIN' tier!
Is this some kind of joke?! Or some serious MM planing from WG?!?
If this is it - here you see a man who'll leave the game after 5 years of playing.
